Steven Chu Suggests A New Finish Line For Electric Vehicles

Scientists building a better battery typically strive for lower cost, lower weight or higher energy density, but Steven Chu, the Nobel Prize-winning former Energy Secretary, just emphasized another metric:

Charging rate…

Chu has mentioned before that he and Yi Cui of Stanford’s Materials Science Department are working on a next-generation battery that could improve energy density five times and charging rate up to ten times over conventional lithium-ion batteries. The new battery would be made from lithium and sulfur.

Argonne National Laboratory’s Joint Center for Energy Storage Research has also identified lithium-sulfur as the most promising successor to lithium-ion in the transportation sector.More>>
